Selecting a specific Collection by name and then deleting it
Use Context


  So I am wanting to select this collection and delete it.


Further to Blender 2.80: Delete Collection or clear the intial scene in scripting mode

As is the case with most of blender making  active in the UI gives it context. 

The context collection can be the scene collection so don't want to delete that.

import bpy
from bpy import context

remove_collection_objects = True

coll = context.collection
scene = context.scene

if coll:
    if remove_collection_objects:
        obs = [o for o in coll.objects if o.users == 1]
        while obs:
            bpy.data.objects.remove(obs.pop())

    if coll is not scene.collection:
        bpy.data.collections.remove(coll)


Remove named collection and its unique objects

Script below will remove the default scene collection "Collection 1" and all objects within it. 

Change name to collection to remove and set the remove_collection_objects toggle.

import bpy
#from bpy import context


name = "Collection 1"
remove_collection_objects = True

#coll = context.collection # 
coll = bpy.data.collections.get(name)

if coll:
    if remove_collection_objects:
        obs = [o for o in coll.objects if o.users == 1]
        while obs:
            bpy.data.objects.remove(obs.pop())

    bpy.data.collections.remove(coll)
